I forgot the link

  [1] http://en.cppreference.com/w/cpp/numeric/complex/conj

Might as well share these for comparison

  [2] http://en.cppreference.com/w/cpp/numeric/complex/arg
  [3] http://en.cppreference.com/w/cpp/numeric/complex/imag
  [4] http://en.cppreference.com/w/cpp/numeric/complex/real

To repeat and clarify, I suspect std::arg, std::imag, and std::real are
ok to use directly, but std::conj differs between compilers, and Octave
wants behavior that differs from the C++ standard anyway.

HTH,
